Tools and Materials You’ll Need
Before you start drilling, you’ll need to gather the following tools and materials:
- Electric drill
- Drill bits (1/8 inch, 1/4 inch, 3/8 inch)
- Center punch
- Hammer
- Safety glasses
- Gloves
Safety First
Before you begin, it’s important to take some safety precautions. Wear safety glasses and gloves to protect yourself from flying debris. Also, be sure to work in a well-ventilated area to avoid inhaling harmful fumes.
Step 1: Locate the Keyhole
The first step is to locate the keyhole. This is usually found in the center of the lock.
Step 2: Mark the Center of the Keyhole
Use a center punch to mark the center of the keyhole. This will give you a guide for drilling.
Step 3: Drill a Pilot Hole
Use a 1/8 inch drill bit to drill a pilot hole in the center of the keyhole. This hole will help to guide the larger drill bits.
Step 4: Drill a Larger Hole
Use a 1/4 inch drill bit to drill a larger hole around the pilot hole. This hole should be large enough to fit the 3/8 inch drill bit.
Step 5: Drill the Final Hole
Use a 3/8 inch drill bit to drill the final hole. This hole should be large enough to break the cylinder lock.
Step 6: Remove the Cylinder Lock
Once you have drilled the final hole, you should be able to remove the cylinder lock by pulling it out of the door.
Step 7: Replace the Cylinder Lock
If you need to replace the cylinder lock, you can purchase a new one at a hardware store. To install the new lock, simply insert it into the door and turn it until it locks.
Tips for Drilling Cylinder Locks
- Use a sharp drill bit. A dull drill bit will make it more difficult to drill the lock and could damage the drill.
- Apply pressure to the drill. Don’t just let the drill spin freely. Apply firm pressure to the drill to help it cut through the metal.
- Drill slowly. Don’t try to drill the lock too quickly. This could cause the drill bit to overheat and break.
- Wear safety glasses and gloves. This will protect you from flying debris and harmful fumes.
